APPARATUS AND METHOD OF ORNAMENTING PAPER Filed July 3, 1929 Patented May 12, 1931 UNITED PATENT OFFICE FRANK G. CRANE AND JOSEPH M. WARD, OF DETROIT, MICHIGAN APPARATUS AND METHOD OF ORNAMENTING PAPER Application filed July 3, 1929. Serial No. 375,817.

The main objects of our invention are: First, to provide an improved apparatus for making striped paper in which the color is applied during the process of manufacture, 5 the lines of color being very distinct and definite.

Second, to provide an apparatus of this character which is very simple and readily embodied in paper making machines of the 10 Fourdrinier type.

' Third, to provide a method of striping paper whereby the color is applied during the process of manufacture.

' Objects pertaining to details and economies '15 of our invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure illustrating the manner of carrying out our invention is clearly illustrated 2 in the accompanying drawings, in which:

Fig. 1 is a fragmentary side elevation of a paper making machine of the Fourdrinier type embodying our improvements, parts being shown in longitudinal section on line 25 11 of Fig. 2 and in conventional form.

Fig. 2 is a fragmentary transverse section on line 2-2 of Fig. 1.

Fig. 3 is an enlarged detail longitudinal section.

In the accompanying drawings 1 represents the breast roll and 2 the forming wire or web of a paper making machine of the Fourdrinier type. The suction box is indicated at 3 and the feed box at 4, one of its discharge gaskets being shown at 5. These parts are shown in conventional form as their structural details form no part of this invention.

Above the forming web I mount a plurality of color troughs 6, 7 and 8 which are preferably arranged in superimposed relation on a cross bar 9 carried by the brackets 10.

The color troughs 6, 7 and 8 are provided with delivery conduits 11, 12 and 13, respectively. These conduits are arran ed with their lower ends in alinement and a j acent to but spaced from the forming web. Each conduit is provided with a wick 14:, the up per ends of which project into the color troughs. The lower ends of the wicks depend from the conduits into wiping engagement with the web of paper or pulp 15 onthe forming web of the paper making machine. The wicks engage the paper and-deliver color thereto in advance of the suction box so that the color is drawn through the web of paper at the suction box.

The conduits of the several troughs are arraged in alternating relation; that is, they are arranged in sets or groups in the embodiment illustrated, although, of course, this arrangement may be varied. The conduits of the several troughs are interposed so that the desired arrangement of color stripes is secured on the web.

By this apparatus and method color is applied to the web with great uniformity and the stripes are distinct and straight. By this method the color is applied economically and a great variety of effects may be secured.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is:

1. The combination with a forming web of a paper making machine and a suction box operatively associated therewith, of a plurality of color troughs disposed transversely above said forming web in superimposed relation in advance of said suction box, a plurality of conduits leading from the several troughs and having their lower ends arranged in alinement and adjacent to but spaced from the forming web, the conduits of the several troughs being arranged in alternating relation, and wicks in said conduits 8 having their lower ends-projecting therefrom into coacting relation to the plup or web of paper on the forming web. v

2. The combination with a forming web of a paper making machine and a suction box operatively associated therewith, of a plurality of color troughs disposed above said forming web in advance of said suction box, a plurality of conduits leading from the several troughs and having their lower ends ar ranged adjacent to but spaced from the forming web, the conduits of the several troughs being arranged in alternating relation, and wicks in said conduits having their lower ends projecting therefrom into coacting relation to the pulp or web of paper on the forming web.

3. The combination with a forming web of a paper making machine and a suction box operatively associated therewith, of a plurality of color troughs'disposed above said forming web in advance of said suction box, a plurality of conduits leading from the sev; eral troughs and having their lower ends arranged adjacent to but spaced from the forming web, and wicks in said conduits having their lower ends projecting therefrom into coacting relation to the pulp or web of paper on the forming web.

4. The combination with a forming web of a paper making machine and a suction box operatively associated therewith, a plurality of color troughs, a plurality of conduits leading'from each of said troughs and arranged in spaced interposed relation transversely of the forming Web and in advance of the suction box, and wicks in said conduits having their lower ends projecting therefrom-into contacting relation to the pulp or web of paper on the forming web.

5. The combination with a forming web of a paper making machine, a plurality of color troughs, a plurality of conduits leading from each of said troughs and arranged in spaced interposed relation transversely of the forming web, and Wicks in said conduits having their lower ends projecting therefrom into 00- acting relation to the pulp or web of paper on the forming web.

6. The combination with a forming web of a paper making machine, of-a plurality of sets of color conduits, the conduits of each set having a separate source of supply, the conduits of the setsbeing arranged in a series of groups, and wicks in said conduits having their lower ends projecting from the conduits into coacting relation to the pulp or web of pa er on the forming web.

' The combination with a forming web of a paper making machine, of a plurality of sets of color conduits, the conduits of each set having a separate source of supply, the-conduits of the sets being arranged in interposed relation transversely of the forming web, and wicks in said conduits having their lower ends projecting from the conduits into coacting relation to the pulp or web of paper on the forming web.

8. The combination with the forming web of a paper making machine and a suction box operatively associated therewith, a color trough disposed above said forming web, a plurality of conduits leading from said trough and having their lower ends disposed adjacent to the forming web, and wicks in said conduits having their lower ends projecting therefrom into contacting relation with the pulp or web of paper on the form.- ing web in advance of the suction box;

9. The combination withthe forming of a paper making machine, of a color trough, a plurality of conduits leading from said trough and spaced transversely of the forming web, and wicks in said conduits having their lower ends projecting therefrom. into coacting relation withthe pulp or web of paper on the forming web.

In witness whereof we have hereunto set our hands.
